Safety Instructions, Warnings, and Notes EN 5LGE PDP 2.

2. Safety Instructions, Warnings, and Notes

Index of this chapter:2.1 Warnings

Notes:• Only authorised persons should perform servicing of this

module.• When using/handling this unit, pay special attention to the

PDP Module: it should not be enforced into any other way then next rules, warnings, and/or cautions.

• "Warning" indicates a hazard that may lead to death or injury if the warning is ignored and the product is handled incorrectly.

• "Caution" indicates a hazard that can lead to injury or damage to property if the caution is ignored and the product is handled incorrectly.

2.1 Warnings

1. Do not touch the Signal and Power Connectors while this product operates. Do not touch EMI ground part and Heat Sink of Film Filter.

2. Do not supply a voltage higher than specified to this product. This may damage the product or can create hazardous situations.

3. Do not use this product in locations where the humidity is extremely high, where it may be splashed with water, or where flammable materials surround it. Do not install or use the product in a location that does no satisfy specified environmental conditions. This may damage the product or can create hazardous situations.

4. If a foreign substance (such as water, metal, or liquid) gets inside the product, immediately turn "off" the power. Continuing to use the product may cause electric shock or can create hazardous situations.

5. If the product emits smoke and abnormal smell, or makes an abnormal sound, immediately turn "off" the power. Continuing to use the product may cause electric shock or can create hazardous situations.

6. Do not (dis)connect the connector while power to the product is "on". It takes some time for the voltage to drop to a sufficiently low level after the power has been turned "off". Confirm that the voltage has dropped to a safe level before (dis)connecting the connector.

7. Do not pull out or insert the power cable from/to an outlet with wet hands. It may cause electric shock.

8. Do not damage or modify the power cable. It may cause electric shock or can create hazardous situations.

9. If the power cable is damaged, or if the connector is loose, do not use the product, otherwise, this can lead to hazardous situations or may cause electric shock.

10. If the power connector, or the connector of the power cable, is dirty or dusty, wipe it with a dry cloth. Otherwise, this can lead to hazardous situations.

11. The PDP module uses a high voltage (max. 450 VDC). Keep the cautions concerning electric shock and do not touch the device circuitry handling the PDP unit. And because the capacitors of the device circuitry may remain charged at the moment of Power "off", standing for 1 minute is required in order to touch the device circuitry.

12. Because the PDP module emits heat from the glass panel part and the drive circuitry, the environmental temperature must not be over 40 deg. C. The temperature of the glass panel part is especially high owing to heat from internal drive circuitry. And because the PDP module is driven by high voltage, it must avoid conductive materials.

13. If inserting components or circuit boards in order to repair, be sure to fix a lead line to the connector before soldering.

14. If inserting high-power resistors (metal-oxide film resistor or metal film resistor) in order to repair, insert it 10 mm away from a board.

15. During repairs, high voltage or high temperature components must be put away from a lead line.

16. This is a cold chassis but you better use an isolation transformer for safety during repairs. If repairing the electricity source part, you MUST use the isolation transformer.

17. Do not place an object on the glass surface of the display. The glass may break or be scratched.

18. This product may be damaged if it is subjected to excessive stresses (such as excessive voltage, current, or temperature). The absolute maximum ratings specify the limits of these stresses.

19. The recommended operating conditions are conditions in which the normal operation of this product is guaranteed. All the rated values of the electrical specifications are guaranteed within these conditions. Always use the product within the range of the recommended operating conditions. Otherwise, the reliability of the product may be degraded.

20. This product has a glass display surface. Design your system so that excessive shock and load are not applied to the glass. Exercise care that the vent at the corner of the glass panel is not damaged. If the glass panel or vent is damaged, the product is inoperable.

21. Do not cover or wrap the product with a cloth or other covering while power is supplied to the product.

22. Before turning on power to the product, check the wiring of the product and confirm that the supply voltage is within the rated voltage range. If the wiring is wrong or if a voltage outside the rated range is applied, the product may malfunction or be damaged.

23. Do not store this product in a location where temperature and humidity are high. This may cause the product to malfunction. Because this product uses a discharge phenomenon, it may take time to light (operation may be delayed) when the product is used after it has been stored for a long time. In this case, it is recommended to light all cells for about 2 hours (aging).

24. This product is made from various materials such as glass, metal, and plastic. When discarding it, be sure to contact a professional waste disposal operator.

25. If faults occur due to arbitrary modification or disassembly, LG Electronics is not responsible for function, quality or other items.

26. Use of the product with a combination of parameters, conditions, or logic not specified in the specifications of this product is not guaranteed. If intending to use the product in such a way, be sure to consult LGE in advance.

27. Within the warranty period, general faults that occur due to defects in components such as ICs will be rectified by LGE without charge. However, IMAGE STICKING due to misapplying the above provision (12), is not included in the warranty. Repairs due to the other faults may be charged for depending on responsibility for the faults.

28. While assembling the PDP module into a set, use the EMI ground part of the Film Filter for grounding, BEFORE removing the protective film, to prevent that static electricity can damage the TCPs or boards

PSU (see figure “PSU trouble shooting“)1. Check each unit part of PSU inside with naked eye

(capacitor, FET, IC, resistor). 2. Check fuse and switch position (on "Normal").3. Check output voltage, which is converted from AC to DC.4. Voltage Check (5V, Va, Vs).

When PSU protection occurred: check for short between Y-SUS and Z-SUS board.

Figure 5-8 PSU trouble shooting

PSU Power ProtectionThere is a power protection when the power is switched "off" automatically within 2-3 min. from power "on".The power protection function protects the boards when a short occurs on circuits of the PDP module, or when a power problem occurs. If there is no power, even after replacing the PSU, find out where the short occurred.

In case of a PSU protection, the red LED will be "on" and an error code will be displayed via the green blinking LED (see also paragraph "Detailed PSU Trouble Shooting" further on).In case of a PSU protection, switch the service switch to "auto", disconnect the power supply connectors to the boards, to find if the boards are defective or the PSU itself.

8.2.4 Internal Test Patterns

The CTRL board is capable of generating it’s own video test patterns. There are two possibilities, both based on R406 and R407:• R406 is open and R407 is fitted (= standard setting): the

test pattern is a full black screen (very low light output).• R406 is fitted and R407 is open (desolder R407 and mount

it on pos. R406): the test patterns are shown in an automatic loop.

Caution: These components and tracks are very fragile, so it will be very easy to damage something! Be careful !
